OK. So how did Bush get elected, not once but twice?
Well, the LSM thought they could sink him in 2000 with his drunk-driving arrest, and in 2004 with the fact that he had Killian rig documents so he could escape duty. Of course, their problem was that there wasn't anything real in George W. Bush's record with which to attack him.
John McCain's record, if properly exposed, will be devastating to him. Even just playing some nicely edited clips of McCain's explosions, followed by a nuked daisy, would probably work pretty well. McCain's record as a flip-flop-flip-flopper is pretty nasty also.
